Phase 1 is complete. Live testing revealed:
- Window size (64240) is already correct — Phase 2 window mangling unnecessary
- TI=Z (IP ID = 0) is the single remaining blocker for Windows spoofing
- ip_no_pmtu_disc does NOT fix TI=Z (tested and confirmed)
Revised phase plan:
- Phase 2: ICMP tuning (icmp_ratelimit + icmp_ratemask sysctls)
- Phase 3: NFQUEUE daemon for IP ID rewriting (fixes TI=Z)
- Phase 4: diminishing returns, not recommended
Added detailed NFQUEUE architecture, TCPOPTSTRIP notes, and
note clarifying P= field in nmap output.
